SPECIFICATION formig part of Letters Patent No. 590,072, dated September14, 18197.

Application filed October 8, 1896. Serial No. soezzo. (No model.) V

i Ta albwwm it may concerns Be it known that I, ORRIN W. PARKER, acitizen of the United States, residing at Oakland, countyof Alameda,State of California, have inventd an Improvement in Wave- Power Pumps;and I hereby declare the following to be a full, clear, and exactdescription of the same.

My invention relates to an apparatus which is especially designed forutilizing the constant motion of the waves and storing up powergenerated thereby.

It consists, essentially, of a fioat resting npon the surface of thewater at a sufficient distance from the land, a frame extending from thefloat to a suitable point, where it is fulcrumed, andconnections-between the frame and a series of pumps by which the pumpsare actuated from the float so as to continually throw water into anelevated receptacle or reservoir, and in connection with this certainmeans for adjusting to suit the high tide or the throw of the stroke tobe given the punps. i

Referring to the accompanying drawings, Figure l is a plan View of mydeviee. Fig. 2 is an elevation of thesame. Fig. 3 is a detail View ofthe means forregulating the pump-stroke.

In the Construction of my apparatus I employ a float A of any suitablesize, form, or Construction, the requirements of such fioat beingconsiderable bu oyancy and adaptability to be readily moved by the riseand fall of the waves. This fioat has a horizontal frame B, one end ofwhich is Secured to the fioat and the other extends inwardly to the landor point of support, where by means of journals at C this frame issupported so that they move easily with the float' Two other frames DeXtend from the outer upper part of the float, converging therefrcm to apoint at a considerable height above the shaft on which the horizontalframe turns. All these frames are preferably made of a truee-pattern togive them sufficient strength to resist torsion without unduly weighingthem down.

In the upper part of the frame C and at the inner end is fixed a stoutpin or trunnion c, which is adapted to be engaged by notches formed inthe adjacent end of a pitman F. The opposite end of this pitman connectswith the upper end of 'a lever G, which lever is fulcrumed 'upon'afra-me H, and the lower end of the lever is 'connected more or lessdirectly with the plungers I of a series of pnmps J. These pumps are of`any suitable or desired size, and by their connections, as here shown,they work in'unison.

The ends ofthe pump-piston opposite to the connection between theplungers and the swinging lever are connected with a suctionchamber L,which in 'turn connects with a reservoir M, Conveniently Situated withrelation thei-eto. a

The reservoir may be filled in various ways. If the wavesaresufficiently high, the water from the breaking waves may be led througha chute N and delivered into this reservoir, or inwardly-opening'valvesor other devices may be employed to keep it supplied;

The suction-cham ber of the pumps connects directly with this reservoirwith suitable inlet-valves, which allows the water to be drawn into thepump-cylinders when the plungers are drawn backward and forced out whenthe plungers are again moved inwardly.

A common main O receives the water from each of these pumps and conductsit to the desired point of` storage, a check-valve being provided toprevent the return of the water after it has' been forced into the main.

The pump-plungers are wthdrawn by the risin g of the fioatand are forcedback to raise the water by the weight of the float* and its connections,when'the title recedes, thus operating the pump by gravity instead ofthe buoyancyof the fioat.

In order to regulate the length of the pitman 'and accommodate it andthe connecting parts to the riseandcfall ofzthe tide, which is sometimesconsiderable, I have shown the pitman formed of 'a 'series of slotChannels or notches t', adaptedto 'en'gage the pin c on the top of the'waveactuated frame D, so that as the tide rises one of the notches maybedisen gaged and another one en gaged in itsplace. This is effected bymeans of a sliding arm Q, movable by means of a lever R, and having theupper end adapted to engagethe pitrnan and aise it whenever desired tochange its position. The pitman is (also jointed centrally, as shown atf, so that if the movement of the fioat is too violent or great for thede- IOO sircd movement of the punps the joint in the the lower part ofthe pitman and insures the breaking of the lock-joint f. The lug g maybe fixed to a slide V, movableupon the upper end of the lever G, and thepitman connection may be carried by the same slide, so as to maintainits relative position to the lu g.

The slide may be raised or lowered on the lever by a screw or othermechanism, so that the relative length from its end to the fulcrum maybe varied to accommodate it to different strokes which it may be desiredto give the plungers.

Stops S prevent too long a stroke of the plungers if the waves are high.

Either of the pumps may be disengaged, if desired, for the purpose ofinspection or repairs without in any way interfering with the others, aseach punp has its own set of Valves.

If it be desired at any time to raise the fioat out of water, I employ aframe, as shown at U, consisting of piles driven into the bottom uponeach side ot' the fioat, and by means of suitable tackle connected withthe frame and with the fioat the latter may be raised at will.

Having thus described my invention, What I claim as new, and desire tosec ure by Letters Patent, is-

1. The combination, of a fioat, a horizontal frame extending therefromand having journaled supports for the inner end, a vertical frameextending above the horizontal one and gradually converging andincreasing in depth from the fioat to the inner end, a pumpcylinder witha plunger working therein, a lever fulcruned between its ends, a jointedadjustable pitman between one end of said lever and the fioat-frame,said lever having its opposite end connected with the pumpplunger.

2. The combination of a fioat adapted to rise and fall by the movementof the waves, a horizontal truss-frame extending inwardly therefrom andhaving the inner end journaled so as to allow the fioat to rise andfall, vertically-disposed truss-franes having the outer ends connectedwith the fioat and m ain frame, said frames approaching each other andincreasingin depth toward the inner end, pumps connected with the sourceof water supply and discharge, having plungers reciprocating therein, alever connected with the pumpplungers at the lower end having the upperend connected with the upper part of the fioatactuated frame byajoint-ed pitman, whereby motion is transmitted to the pl un gers and itsaction thereon is limited.

3. The combination of a fioat adapted to be moved by the rise and fallof the waves, a horizontal truss-frame extending therefrom toward theland, journals about which the inner end is turnable when the fioatrises and falls, truss-frames extending from the fioat, converging andincreasing in height toward the inner end, a pin or trunnion fixed atthe top of said frame, a pitman having different points of connectionwith said pin whereby the length may be regulated, a lever with whichthe upper end of the pitman connects, the lower end of said lever beingconnected with a group of pumps whereby the plungers thereof arereciprocated, and a reservoir or source ot` supply, and a discharge withwhich said pumps are connected.

4. The combination of a fioat adapted to rise and fall by the movementof the waves, a truss-frame eXtending from the fioat inwardly toward theshore, horizontally-disposed j ournals about which the frame and fioatrise and fall, pu mps connected With the source of supply and discharge,plungers reciprocating therein, a lever with the lower end of which thepump-plungers are connected to work in unison, a jointed adjustablepitman having one end connected with the upper end of said lever havingthe opposite end adapted to engage the pin upon the fioat-moved leverand a slide and lever-arm whereby the pitman may be raised and shif ted'to change its connection with the float-frame.

5. The combination of a fioat adapted to rise and fall by the movementof the waves, a truss--franie extending from the fioat inwardly towardthe shore, horizontally-disposed j ournals about which the frame andfioat rise and fall, pumps connected with a source of supply, plungersreciprocating therein, a lever with the lower end of which thepumpplungers are connected, a jointed adjustable pitman connecting thepump-actuating lever with the reciprocating float-actuated frame, a lugupon the lever adapted to contact with the pitman and break the joint atthe end of the stroke, and a slide carrying the lug and the pitmanconnection, and adjustable to Or from the lever-fulcrum. p

In witness whereof I have hereunto set my hand.
